HZZL-3 ASTM D971 Transformer Oil Interfacial Tension Meter

Product Introduction

The ASTM D971 Transformer Oil Interfacial Tension Meter is a simple and easy to use testing instrument that uses physical methods instead of chemical methods. The amount of intermolecular tension reflects the physicochemical properties of the liquid sample and is one of the important indicators of product quality. And our ASTM D971 Transformer Oil Interfacial Tension Meter with automatic interfacial tension meter can quickly and accurately measure the surface and interfacial tension values of various liquids, and display the results automatically.

Features

Our ASTM D971 Transformer Oil Interfacial Tension Meter has won the favor of users in the market with its good performance and reasonable price. It adopts electromagnetic force balance type sensor to improve the measurement accuracy, and it is very convenient to adjust the instrument by calibrating one point. It is integrated temperature detection circuit, which automatically compensates the temperature for the test results. The instrument has RS232 interface device, which can be connected with computer to facilitate data processing.

Technical Characteristics

Matters needing attention

1. Working environment:

The working environment of the instrument should meet the requirements mentioned in Chapter 4.

2. Platinum ring:

The plane of the ring should be parallel to the page on the north side, and the ring must maintain a certain degree of roundness. The platinum ring should be clean. It can be cleaned with detergent, then rinsed thoroughly with pure water. After cleaning, heat the platinum wire in the oxidizing flame of an alcohol lamp until it glows orange-red.

3. Test cup:

The test cup should be clean, and it can be cleaned and washed, then rinsed with hot water, and finally rinsed with pure water, and drained before use.

4. Obtaining pure water:

It is best to use distilled water that has been purified multiple times. Tests have shown that some commercially available purified drinking water can meet the experimental requirements.

5. Calibration of the instrument:

After the instrument is subjected to a large impact, or after moving, the weight in the setting items should be calibrated.

Compared with similar products, our Fully Automatic Liquid Interface Tension Tester for Synthetic Blood (IT-800A) has higher quality and more favorable price, so it is deeply loved by consumers in the market.
